Folded Diana Verdigris

#40bab9
Notes

Folded Diana Verdigris (#40BAB9) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (180°, 49%, 49%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Folded
adjective

Old English fealdan, to fold — past-participle of fold. As a color modifier, folded implies a clear-and-creased-and-arranged quality where the hue carries the visual register of carefully-folded-and-neatly-arranged textile surface. Sits at the crisp-and-finished end of the grid, parallel to pressed and trim in usage.

Diana
modifier

Latin Diana, Roman-goddess-of-moon-and-hunt. As a color modifier, diana implies a Roman-goddess-and-moon-and-hunter-and-virgin quality, the visual register of Roman-Diana-and-Ephesian-Artemis hand-Roman-goddess-and-moon-and-hunter-and-virgin Roman-Diana-and-Ephesian-Artemis-and-Lake-Nemi diana-and-Roman-goddess-and-moon-and-hunter surfaces under Roman-Diana-and-Ephesian-Artemis-and-Lake-Nemi Aventine-Hill-and-Nemi-grove moonlit-grove-light. Sits at the modifier-and-myth end of the grid, parallel to luna and hera in usage.

Verdigris
noun

The basic copper carbonate that forms on weathered copper and bronze — the pigment scraped from oxidized metal and used in Renaissance painting before being supplanted by more stable greens. The color refers to a thick verdigris on aged copper roofing or the Statue of Liberty's surface: a soft, slightly muted blue-green with the powdery finish of mineral oxide. Cooler than patina, warmer than seafoam, with the archaeological weight of a mineral made by time.
